The moon : her motions, aspect, scenery, and physical condition
The Moon: Her Motions, Aspect, Scenery, and Physical Condition is an 1873 astronomy book by Richard A. Proctor, published in London by Longmans, Green, and Co., written for general readers interested in lunar science. Its pictures are plain black-and-white geometric diagrams of orbits, sphere projections, and angle measurements drawn with fine lines and lettered points, useful to a designer wanting technical schematic linework and labelled construction drawings.
